Abstract: 523,792. Rolling dough. VICARS, Ltd., T. & T., GRAINGER, G. F. W., and CROSLAND, E. M. Jan. 14, 1939, No. 1292. [Class 87 (ii)] In the preparation of dough for making bakery products of a flaky texture from a continuous sheet of dough, the dough is cut into a number of bars or ribbons which are then overlapped and the wad of overlapped bars or ribbons passed through rolls to form a continuous sheet. In one form of the apparatus, the dough sheet 8 carried by a conveyer 4 on which it is deposited from sheeters 1, 7, with if desired, an interposed layer of flour, fat &c. from a distributer 5, is fed through gauging rollers 9 on to one of which rotary cutters 10 contact to reduce the dough sheet to narrow longitudinal strips. The strips'are received on a conveyer 12 which is oscillated in a horizontal plane and delivered therefrom in wavy form to a wider conveyer 17 moving at a reduced speed to cause the wavy strips to overlap, the overlapped strips finally being pressed to a continuous sheet by rollers 18. In another -form of the apparatus; the sandwiched sheet of dough 22, Fig. 3, carried by a conveyer 23 is cut into transverse strips 31 by a reciprocating cutter 25 and the strips, spread apart by a faster moving conveyer 26, are delivered therefrom by a fripping motion at its delivery end to a slower moving conveyer 27 running at right angles thereto. The overlapped strips on the latter are reduced to a continuous sheet by further gauging rollers. Groups of dough strips on the conveyer 27 may be disposed at an angle to other groups of dough strips. The cutters may be replaced by fluted rollers.

Abstract: 260,453. Douthitt, F. H. Jan. 18, 1926. Spray evaporators.- In drying milk, malt extract, fruit juices, eggs, &c., the liquid is sprayed through a nozzle 53 into a chamber into which air forced by a blower 60 through a heater 62 enters by downwardly and obliquely directed nozzles 65, and passes in a circular path towards the bottom of the chamber, and then rises along the axis to the outlet 36. The dried product is cooled in the base of the chamber by air forced by a blower 80 over cooling coils 82 and entering by ducts 88, and is discharged through an outlet 90 and a distintegrator 92 in which it is forced by a blower 93 through spirally arranged pipes in which the lumps are broken up by being thrown against the walls, which are roughened or have projecting ribs or baffles. The product passes by a pipe 94 to collecting vessels 95, 96. The air from the discharge outlet 36 passes into a chamber 28 into which fresh liquid is sprayed in order to be preheated and to separate suspended particles from the air. Liquid to be evaporated is forced by a pump 16 from a vat 10 through a pipe 17 and a valve 18 controlled by a float 40 into the chamber 28, and is drawn from its base by a pump 21 which passes it in part by a pipe 30 to a pump 51 which sprays it into the drying chamber, and in part by a pipe 24 to pipes 26, 32 carrying spray nozzLes in the chamber 28. The liquid in the vat, 10 and chamber 28 may be circulated through devices 13, 23 which may be pasteurizers, heaters, or coolers and returned to the vat or chamber by pipes 14, 30. A device 71 carrying chains 70 which scrape over the walls is caused to rotate in the drying chamber by the currents of air acting upon vanes 74.

Filed: 1955-01-19
Abstract: 790,858. Automatic bobbin-changing in looms. BRITISH COTTON INDUSTRY RESEARCH ASSOCIATION. Jan. 19, 1956 [Jan. 19, 1955], No: 1575/55. Class 142(2) The old and new weft trails 14, 15 are kept clear of the fabric, after being cut at the selvedge, by individual suction nozzles 23, 13. The nozzle 23 is mounted on the shuttle feeler 24 and its mouth is provided with a barb 23a over which the weft thread snaps, as the feeler moves rearwards, to prevent the thread from escaping as the feeler returns to the front of the loom. When the temple cutter 20 operates, the free end of the weft trail 14 is drawn into the nozzle, the other end being still held by the shuttle eye cutter and clamp 17 until the next replenishing operation when opening of the cutter allows the weft trail 14 to be drawn completely into the nozzle 23. The nozzle 13 is fixed with its mouth at the inner side of the notched disc 19. When the temple cutter operates, the new weft trail 15 is drawn into the nozzle 13, but remains attached to the hub 18; owing to the turning of the hub at each replenishment, the weft trails encounter a hook 21 by which they are gradually drawn out of the nozzle and become wound on the hub (which may be larger in diameter than usual to speed up this action). Instead of being on the shuttle feeler, the nozzle 23 may be fixed near to the shuttle eye cutter and clamp 17.

Patent GB-606745-A (GB)
Title: Improved process for the manufacture of peroxide compounds by oxidation of amalgams
IPC: C01B15/12
Filed: 1946-01-17
Abstract: Peroxide compounds, e.g. hydrogen peroxide and perborates, are made by oxidizing an alkali amalgam with oxygen in the presence of water. The alkali amalgam should contain more than 100 and preferably between 2000 and 100,000 atoms of mercury per atom of alkali metal; an amalgam from an alkali electrolysis mercury cathode may be used. Oxygen may be introduced as air or mixed with carbon dioxide or carbon monoxide; its concentration may be increased by raising the pressure, lowering the temperature, or mixing another liquid, e.g. an alcohol, with the water.  Promoting substances which may be added are cyanides, fluorides, borates, sodium silicate, phenol, azo compounds, quinones and known stabilisers for peroxides.  The addition of boric, sulphuric, or carbonic acid serves to adjust the pH and to form persalts.  Milk of lime may be added to react with the hydrogen peroxide formed. The reaction mixture should be vigorously stirred or the amalgam may be passed into or through the liquid in fine drops or as a spray.  In examples, sodium and potassium amalgams are reacted with water and 90 per cent methyl alcohol, producing hydrogen peroxide and sodium perborate, and sodium carbonate as a by-product. A cyclic process is described in which spent amalgam is replaced in the reaction chamber by fresh amalgam; aqueous liquid is withdrawn and treated with carbon dioxide and boric acid or borax to precipitate sodium perborate, sodium carbonate crystallised out, and the mother liquor returned to the process.

Abstract: 1,222,972. Texturing yarns. M LEFEBVRE. 11 Jan., 1968 [12 Jan., 1967: 23 March, 1967], No. 1693/68. Headings D1F and D1W.  A yarn is textured by means of an air stream in which shock waves are produced to deform the yarn, the air stream being heated and/or the yarn being preheated to set the deformations in the yarn. The shock waves are produced by the speed of the air flow changing from supersonic to subsonic, or by an ultrasonic generator which may be controlled by amplified signals from a microphone which picks up the waves from a control yarn positioned in a venturi. One or more airy ducts are directed radially into a chamber through which the yarn passes or tangentially in order to false twist the yarn. If there is more than one tangential entry duct the rotating flows produced may be in the same or opposite directions. The yarn may pass in succession through two chambers having opposite directions of air flow. The tension on the yarn may be periodically varied so that the yarn periodically moves from the outer boundary of the rotating air flow to the inner boundary so that an alternatively twisted yarn is produced. There may be feed pipes from a dye bath connected to the air duct or ducts so that the dye liquid can be evaporated and dye the yarn while the yarn is spread out in the chamber. Two different dyes may be injected at different places so as to dye the yarn interior and exterior differently.

Filed: 1943-02-04
Abstract: 568,205. Discharge apparatus. AKT.- GES. BROWN, BOVERI, & CIE. Feb. 4, 1943, No. 1889. Convention date, Jan. 26, 1942. [Class 39 (i)] An electron discharge device has a number of anodes b1, b2, b3, b4 and b5 for each phase connected together by resistances c1, c2, c3 and c4, the current being supplied direct to anode b1 and a device being associated with each anode to control the resistance of the arc path. These devices serve to break the arc between cathode d and anodes b1 &c. in succession. The effect of the successive increasing resistances thus incorporated in the circuit is to diminish the voltage surge when the arc is finally broken. In the example shown, the devices are extinguishing grids, as described in Specifications . 409,33] and 430,915. Their action may follow automatically in the operation of the first grid e1 by switch g through transformers h1, h2, h3 and h4. The setting up of an arc from anode b2 onward has the effect of energizing the blocking grid of the particular anode and thus passing on the arc to the next anode. As extinguishing devices, electromagnetic fields or electrostatic combined with electromagnetic, can be used instead of grids. A gas blast circuit-breaker may be placed in series with the discharge device.
